About These Birds
Common Kingfisher
The common kingfisher is a dazzling jewel of waterways, its iridescent blue plumage caused by light refraction in the feather structure rather than pigment. These birds inspired the design of the Shinkansen bullet train in Japan — the shape of their bill was copied to reduce sonic booms when trains exit tunnels.
Black-capped Kingfisher
The Black-capped Kingfisher is a Vulnerable, vividly colored kingfisher of South and Southeast Asian coasts and wetlands, with a striking black cap, white collar, blue-purple upperparts, and rufous underparts. It breeds in East Asia and winters south to South and Southeast Asia along coastal mangroves, tidal flats, and wetland margins. It feeds on fish, crabs, and large insects.
